wxPython在Windows和Ubuntu上给出了不同的结果

我已经开发了一个小的wxPython程序，它在Windows和Ubuntu中给出了完全不同的输出（我很高兴被告知我已经错误地编程了，所以我会认为这是一个结果 – 只要我们能够使它工作）

该程序右侧显示四个形状。 双击右侧的图像将它们移动到左侧，反之亦然。

Windows上的问题（请参阅在Windows和Ubuntu中执行相同操作之后拍摄的屏幕截图）：button无法正确呈现; 当我点击十字，圆柱或正方形时，它们正确地移动到屏幕的左侧，但三angular形的多个图像仍然保留; 一个图像出现在左上angular

这些问题都没有出现在Ubuntu中
